Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries recently making headlines in Houston across energy and space tech.

Samra Nawaz, CEO and co-founder of WellWorth

As much as she loves a good Excel spreadsheet, Samra Nawaz had just about had it with the convoluted — and not always completely accurate — process of building financial models within upstream oil and gas.

"Excel is generally a good tool to automate workflows and build really robust spreadsheets. I live in Excel — I have a spreadsheet for everything," Nawaz says on the Houston Innovators Podcast. "What Excel is not is a database."

Engineering teams work with massive amounts with data that's too big for Excel, she explains, so finance teams then have to work off of aggregated data to build their financial models. She was ranting about why there isn't a better process to her husband, Vinay Acharya, who suggested that they build it themselves. Read more.

As much as she loves a good Excel spreadsheet, Samra Nawaz had just about had it with the convoluted — and not always completely accurate — process of building financial models within upstream oil and gas.

"Excel is generally a good tool to automate workflows and build really robust spreadsheets. I live in Excel — I have a spreadsheet for everything," Nawaz says on the Houston Innovators Podcast. "What Excel is not is a database."

Engineering teams work with massive amounts with data that's too big for Excel, she explains, so finance teams then have to work off of aggregated data to build their financial models. She was ranting about why there isn't a better process to her husband, Vinay Acharya, who suggested that they build it themselves.



After thinking it through together, the duo co-founded WellWorth in 2018. Since then, the company has developed its MVP, completed a few accelerators — Rice University's OwlSpark, MassChallenge, and Softeq Ventures, to name a few — and won this year's Startup Pitch Competition hosted by the Ion.

Now, the bootstrapped startup looks to 2024 to bring on its first venture capital investors and team members — first to thoroughly tackle upstream O&G before expanding into other parts of the energy sector, including renewables.

"We're focusing on a specific workflow, and that is for engineering and finance teams and automating the corporate financial modeling side of the workflow," Nawaz says. "But we also see a lot of the renewables companies sprouting up, and we understand the attention on renewables verticals is only going to increase in the next few years.

"We're building WellWorth in a very modular way, so that when the time is right, we can easily start working with customers in the renewable space as well," she adds.

Nawaz, CEO of WellWorth, shares more about her company's growth plan and the impact the technology has on its early customers on the podcast.

Houston energy startup wins Ion's annual showcase, pitch competition

1st place

The Ion hosted its annual startup pitch competition, and one company walked away with a win.

WellWorth, a financial modeling and analysis software-as-a-service company for the upstream energy sector, won the Houston Startup Showcase + Expo and secured a $5,000 prize. The startup's technology introduces a more streamlined approach to NAV modeling or corporate financial modeling for its users.

“Having worked in investment banking, I have seen firsthand how the limitations of Excel models and a lack of bespoke tools have led to inefficient workflows in upstream Oil & Gas finance," says Samra Nawaz, CEO and Co-founder of WellWorth, in a statement. "We decided to solve this problem by building a cloud-based platform that helps energy finance leaders improve decision-making around raising, managing, and deploying capital.”

Nawaz explains how impactful the opportunity to pitch has been on WellWorth, which aims to raise funding early next year accelerate customer acquisition and product development.

“By getting involved in the Ion’s innovation ecosystem, we’ve been able to not only network with many entrepreneurs and innovators in the Houston community, but also find opportunities to scale our growth,” continues Nawaz. “We’re thrilled to have brought a few more customers onboard recently, and are working closely with them to optimize our product pipeline."

The company pitched alongside the other five finalists, which included Tierra Climate, MRG Health, BeOne Sports, Trez, and Mallard Bay. Mallard Bay, a booking platform for hunting and fishing trips, secured the people's choice award, which was decided by the crowd.

“Our flagship event, Houston Startup Showcase, not only connects startups and entrepreneurs with top business leaders but also provides them an opportunity to pitch their innovations to the technology ecosystem,” says Jan Odegard, executive director of the Ion, in a news release. “We extend our congratulations to WellWorth and the company’s innovative SaaS platform for energy industry finance teams, as well as Mallard Bay, the People’s Choice winner. These companies are exemplifying the exciting new technologies being developed in Houston today.”

In addition to the pitches, several companies showcased at the event, including Nanotech, manufacturer of thermal management materials for the built environment; last year's winner Unytag, a universal toll tag that provides drivers the ability to pass through tolls anywhere in the nation; and Softeq, provides early-stage innovation, technology business consulting, and full-stack development solutions to enterprise companies and innovative startups.

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”

Houston hospital performs first fully robotic heart transplant in the U.S.

robotic surgery

A team at Baylor St. Luke’s Medical Center, led by Dr. Kenneth Liao, successfully performed the first fully robotic heart transplant in the United States earlier this year, the Houston hospital recently shared.

Liao, a professor and chief of cardiothoracic transplantation and circulatory support at Baylor College of Medicine and chief of cardiothoracic transplantation and mechanical circulatory support at Baylor St. Luke’s Medical Center, used a surgical robot to implant a new heart in a 45-year-old male patient through preperitoneal space in the abdomen by making small incisions.

The robotic technology allowed the medical team to avoid opening the chest and breaking the breast bone, which reduces the risk of infection, blood transfusions and excessive bleeding. It also leads to an easier recovery, according to Liao.

"Opening the chest and spreading the breastbone can affect wound healing and delay rehabilitation and prolong the patient's recovery, especially in heart transplant patients who take immunosuppressants," Liao said in a news release. "With the robotic approach, we preserve the integrity of the chest wall, which reduces the risk of infection and helps with early mobility, respiratory function and overall recovery."

The patient received the heart transplant in March, after spending about four months in the hospital due to advanced heart failure. According to Baylor, he was discharged home after recovering from the surgery in the hospital for a month without complications.

"This transplant shows what is possible when innovation and surgical experience come together to improve patient care," Liao added in the release. "Our goal is to offer patients the safest, most effective and least invasive procedures, and robotic technology allows us to do that in extraordinary ways."
